Description

Technical Field

[0001] This utility model belongs to the field of dining table technology, and in particular relates to a single-sided pull-out and spring-loaded functional rack. Background Technology

[0002] In existing dining table designs, with the increasing number of family gatherings and social occasions, tabletop space often becomes insufficient. Although some dining tables have extension functions, most require manual operation and the process is cumbersome, failing to meet users' needs for quick and convenient tabletop expansion. Therefore, it is necessary to design a dining table extension shelf with an automatic spring-loaded mechanism. Utility Model Content

[0003] The purpose of this utility model is to address the aforementioned technical problems by providing a single-sided pull-out automatic spring-back extension shelf for dining tables. This shelf can conveniently expand the dining table space and has an automatic spring-back feature, eliminating the need for manual resetting by the user.

[0004] In view of this, the present invention provides a single-sided pull-out and rebound functional rack, including a fixed bracket, a fixed table board fixedly connected to the top of the fixed bracket, a rebound spring screwed onto the inner wall of the fixed bracket, a rotating rod screwed onto one end of the rebound spring and screwed onto the inner wall of the fixed bracket, a connecting rod screwed onto one end of the rotating rod, a movable bracket screwed onto one end of the connecting rod, a movable table board fixedly connected to the top of the movable bracket, a limit guide rail provided on one side of the inner wall of the fixed bracket located on the movable table board, a positioning spring fixedly connected to the inner wall of the limit guide rail, a lifting plate fixedly connected to the top of the positioning spring, a pull rod fixedly connected to the bottom end of the lifting plate, a ratchet fixedly connected to the top of the lifting plate, a toothed block slidably connected to the inner wall of the limit guide rail at the top of the ratchet, and a connecting block fixedly connected to the outer wall of the toothed block and fixedly connected to the outer wall of the movable bracket.

[0005] Based on the above structure, the pull rod movement causes the lifting plate to slide downward against the elastic force of the positioning spring, so that the ratchet and the tooth block move away from each other. At this time, the return spring drives the rotating rod to rotate through its own elastic force. The rotation of the rotating rod drives the tooth block on the outer wall of the movable bracket to slide in the opposite direction through the connecting rod, thereby realizing the automatic reset operation of the movable table.

[0006] Preferably, the rotation center of the rotating rod coincides with the midpoint of the rotating rod. In this embodiment, it is convenient for the rebound spring to drive the rotating rod to rotate through its own elastic force. By setting the rotating rod, it is beneficial to avoid the rebound spring being too long, which would cause the movable bracket to slide unstably.

[0007] Preferably, the movable support forms a telescopic structure with the limiting guide rail through the rotating rod and the connecting rod. In this embodiment, the rebound spring drives the rotating rod to rotate through its own elastic force. The rotation of the rotating rod drives the toothed block on the outer wall of the movable support to slide in the opposite direction through the connecting rod, thereby realizing the automatic reset operation of the movable table.

[0008] Preferably, the movable support is in the shape of an I-beam. In this embodiment, setting the movable support in the shape of an I-beam helps to improve the structural strength of the movable support.

[0009] Preferably, the fixed tabletop and the movable tabletop are parallel. In this embodiment, collisions between the movable tabletop and the fixed tabletop are avoided during the extension and retraction of the movable tabletop.

[0010] Preferably, the ratchet is triangular in shape and the tooth block is inverted triangular in shape. In this embodiment, it is convenient to perform multi-level adjustment of the movable table.

[0011] Preferably, the connecting block forms a positioning structure with the limiting guide rail through ratchet and toothed block. In this embodiment, the positioning spring can use its own elastic force to drive the ratchet and toothed block at the top of the lifting plate to engage, thereby realizing the unfolding operation of the movable bracket.

[0012] The beneficial effects of this utility model are:

[0013] 1. This single-sided pull-out and rebound function frame, by setting ratchet and toothed block, allows the operator to pull the movable bracket, which slides and causes the toothed block on the outer wall of the connecting block to slide along the outer wall of the limiting guide rail. When it slides to the predetermined position, the positioning spring uses its own elasticity to drive the ratchet and toothed block at the top of the lifting plate to engage, thereby realizing the unfolding operation of the movable bracket.

[0014] 2. This single-sided pull-out and rebound function frame, by setting a rotating rod, the movement of the rod drives the lifting plate to slide downward against the elastic force of the positioning spring, so that the ratchet and the tooth block move away from each other. At this time, the rebound spring drives the rotating rod to rotate through its own elastic force. The rotation of the rotating rod drives the tooth block on the outer wall of the movable bracket to slide in the opposite direction through the connecting rod, thereby realizing the automatic reset operation of the movable table.

[0021] The following is in conjunction with the appendix Figure 1 - Figure 4 This application will be described in further detail.

[0022] In this application, the terms "upper," "lower," "left," "right," "front," "rear," "top," "bottom," "inner," "outer," "middle," "vertical," and "horizontal," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.

[0023] This application discloses a single-sided pull-out and rebound functional frame, including a fixed bracket 1, a fixed table 2 fixedly connected to the top of the fixed bracket 1, a rebound spring 3 screwed onto the inner wall of the fixed bracket 1, a rotating rod 4 screwed onto one end of the rebound spring 3 and screwed onto the inner wall of the fixed bracket 1, a connecting rod 5 screwed onto one end of the rotating rod 4, a movable bracket 6 screwed onto one end of the connecting rod 5, a movable table 7 fixedly connected to the top of the movable bracket 6, a limiting guide rail 8 provided on one side of the movable table 7 on the inner wall of the fixed bracket 1, a positioning spring 9 fixedly connected to the inner wall of the limiting guide rail 8, a lifting plate 10 fixedly connected to the top of the positioning spring 9, a pull rod 11 fixedly connected to the bottom of the lifting plate 10, a ratchet 12 fixedly connected to the top of the lifting plate 10, a toothed block 13 slidably connected to the inner wall of the limiting guide rail 8 at the top of the ratchet 12, and a connecting block 14 fixedly connected to the outer wall of the toothed block 13 and fixedly connected to the outer wall of the movable bracket 6.

[0024] Based on the above structure, the movement of the pull rod 11 causes the lifting plate 10 to slide downward against the elastic force of the positioning spring 9, so that the ratchet 12 and the tooth block 13 are far apart. At this time, the return spring 3 drives the rotating rod 4 to rotate through its own elastic force. The rotation of the rotating rod 4 drives the tooth block 13 on the outer wall of the movable bracket 6 to slide in the opposite direction through the connecting rod 5, thereby realizing the automatic reset operation of the movable table 7.

[0025] In one embodiment, the rotation center of the rotating rod 4 coincides with the midpoint of the rotating rod 4.

[0026] In this embodiment, the spring 3 can drive the rotating rod 4 to rotate by its own elastic force. By setting the rotating rod 4, it is beneficial to avoid the spring 3 being too long, which would cause the movable bracket 6 to slide unstably.

[0027] In one embodiment, the movable bracket 6 forms a telescopic structure with the limiting guide rail 8 via the rotating rod 4 and the connecting rod 5.

[0028] In this embodiment, the rebound spring 3 drives the rotating rod 4 to rotate through its own elastic force. The rotation of the rotating rod 4 drives the toothed block 13 on the outer wall of the movable support 6 to slide in the opposite direction through the connecting rod 5, thereby realizing the automatic reset operation of the movable table 7.

[0029] In one embodiment, the movable support 6 is in the shape of an I-beam.

[0030] In this embodiment, by setting an I-shaped movable support 6, the structural strength of the movable support 6 is improved.

[0031] In one embodiment, the fixed tabletop 2 is parallel to the movable tabletop 7.

[0032] In this embodiment, collisions between the movable tabletop 7 and the fixed tabletop 2 are avoided during the extension and retraction of the movable tabletop 7.

[0033] In one embodiment, the ratchet 12 is triangular in shape, and the tooth block 13 is inverted triangular in shape.

[0034] In this embodiment, it is convenient to perform multi-level adjustment operations on the movable table 7.

[0035] In one embodiment, the connecting block 14 forms a positioning structure with the limiting guide rail 8 through the ratchet 12 and the tooth block 13.

[0036] In this embodiment, the positioning spring 9 can use its own elasticity to drive the ratchet 12 at the top of the lifting plate 10 to engage with the tooth block 13, thereby realizing the unfolding operation of the movable bracket 6.

[0037] In this embodiment, when the single-sided pull-out and rebound function frame is in use, the operator first pulls the movable bracket 6. The movable bracket 6 slides and drives the toothed block 13 on the outer wall of the connecting block 14 to slide along the outer wall of the limiting guide rail 8. When it slides to the predetermined position, the positioning spring 9 drives the ratchet 12 at the top of the lifting plate 10 to engage with the toothed block 13 through its own elasticity, so as to realize the unfolding operation of the movable bracket 6.

[0038] Next, after the movable table 7 is used up, the staff pulls the lever 11. The movement of the lever 11 causes the lifting plate 10 to slide downward against the elastic force of the positioning spring 9, so that the ratchet 12 and the tooth block 13 are separated. At this time, the return spring 3 drives the rotating rod 4 to rotate through its own elastic force. The rotation of the rotating rod 4 drives the tooth block 13 on the outer wall of the movable bracket 6 to slide in the opposite direction through the connecting rod 5, thereby realizing the automatic reset operation of the movable table 7.
